Abstract: A method for determining object position information indicative of the position includes at least the horizontal position of an object that is intended to be removed using an object removal machine. The method uses a working machine that includes an implement, and that is different from the object removal machine. The method includes arranging the implement such that at a position of at least a portion thereof has a determinable relation to the position of the object; determining the position of the implement, and determining the object position information using the position of the implement.

Abstract: The invention relates to a method of controlling the working scheme (30, 32) of an autonomous working machine (100) at a work site (1). The method comprises the steps of: determining (S10) the absolute position of a plurality of locations (10) of interest at the work site based on position data from a plurality of position sensors (19) distributed at the work site; generating (S20), by means of a computer, a set working scheme (30) based on the position data; and executing (S30) the set working scheme by the working machine.

Abstract: The present invention relates to a method for determining object position information indicative of the position, including at least the horizontal position, of an object that is intended to be removed using an object removal machine. The method uses a working machine being different from the object removal machine and including an implement. The method includes: arranging the implement such that at a position of at least a portion thereof has a determinable relation to the position of the object; determining the position of the implement, and determining the object position information using the position of the implement.
